Our invention -relates to steel building structures and to an improved method of erecting the same.

An object of the invention 1s to produce s a steel structure which may be assembled Without the use of rivets.

Another object of the invention 1s to provide improved structural steel elements which may be formed at the factory with interengaging means so as to enable their assembl into a building structure at the point o operations without the use Aof specialtools or equipment.

A further object of the invention is to 5 design a building structure which will result in a great saving of time, labor and expense in the production thereof.-

A still further object of the invention is to provide improved and novel means for securing the steel elements together.

Other objects and advantagesof the 1nvention willbecome apparent during the course of the following detailed description when read in conjunction with the accompanyingdrawings, which f orm a part "of this specification, and in which:

Figure 1 is aside elevation of a bullding structure, constructed according to our 1nvention;

Fig. 2 is a similar view taken at rlght angles to Fig. 1;

Fig. 3 is a horizontal sectional vlew taken on the line 3-3 of Fig. 1;

Fig. 4 is a vertical sectional view taken on the line 4 4 of' Fig. 3;

Fig. 5 is a perspective disassembled view of the elements of the invention, illustrating the method of assembly; and

Fig. 6 is a perspective view of one of the locking pins employed in the invention.

Referring now to the drawings in detail wherein a preferred embodiment of the invention is shown by way of example, and whereinl like numerals refer to like parts throughout the same, 1() indicates a suitable foundation or base to which the lower ends 11 of a plurality of spaced upright column members 12, 13 and 14 are anchored in any conventional manner illustrated at 15. 50 While only three upright columns are shown 'posed anges of adjacent upright columns by way of example it -will of course be understood that any number may be employed depending upon the size of the building to be constructed. The columns 12, 13 and 14 arev preferably in the form of I-beams as usually used in structural steel work.

Each of the columns 12, 13 and 14 supports a superposed column 16, 17 and 18 respectively. The columns 16, 17 and 18 are also preferably' I-beams and are disposed in vertical alinement and in end to end relationship with respectI to their supporting columns 12, 13 and 14.

Referring particularly to Figs. 3 and 5, it will be seen that the outer faces of the flanges 19 and 20 of each of the upright collurns 12, 13 and 14 are provided with a socket member 21 adjacent the upper end thereof. Each of the socket members 21 comprises a U-shaped strap having the web n portion 22 spaced .from the surface of the flanges 19 and 2O and having the legs 23 thereof formed integral with. said flanges at the time of manufacture or rigidly secured thereto in any suitable manner such as welding before the columns leave the factory. It will be clearly seen that the U-shaped straps define a rectangular upwardly opening socket 24 with the face of the flanges of the I-beam. 80

The superposed columns 16, 17 and 18 vhave the outer faces ofthe flanges thereof also provided with vertically disposed sock-V et members 25 adjacent the lower and upper ends thereof, the sockets 25 being in 8 vertical alinement and in spaced relation with respect to the sockets 21 on the lowermost set of columns. Suitable horizontal I-beams or girdersv 26 extend between the opand each of these horizontal beams are provided at their ends with vertically disposed plates 27 which are disposed in a plane at right angles to the longitudinal direction of the beam. The plates 27 areeither formed o" integral with the end of the beam or are rigidly secured thereon at the factory. The outer face of each of the plates 27 is provided with va pair of vertically spaced downwardly extending tongue members 28 and 29. 100

Each of the to e members at their upper ends being rovided with a thickened p ortion the plate and sefrvitililg to space the epending ion o e fromsaid plate. en the I-beam 26isinpositioninthebuildingthe tongues 28 and 29 engage in the socket portions 24 of the socket members 21 and 25 respectively thereby the cross beamto the vertical columns and also serving to lock the meeting ends of the vertical columns from lateral dis lament.

Each o the vertical columns is formed solid at their in ends, the channels 31 and 32 on o posite sides of the web portion 33 thereof lia iller blocks l34 and 35 seated therein. e filler blocks 34 andV 35 are rigidly secured in place within the channels of the vertical columns and have their outer faces disposed Hush with the edges of the Bange portions thereof. The filler blocks 34 and 35 are formed with socket members 36 and 37, respectively, of similar construction to the socket members 21 and 25 on the flange portions of the vertical col- The horizontal I-beams 38 extending between the opposite channel faces of adjacent column members are also provided with verfaces thereof as shown in Fig. 5, we have provided locking plates 47a and 48a which areprovided with spaced tongue members for engagement with the sockets carried by the spacer blocks and the faces of the flange portions of vertical columns, the locking plates be also .provided with registering sleeve portions 49 and 50 for the reception of a locking pin 46. vIt will thus be seen that the ends of the radiating horizontal beams in addition to having the tongue portions thereof engaged within the sockets on the vertical columns, will all be locked together to form an in l structure by reason of the registering vs eeve portions thereof being locked together by the tapered pins 46.`

A building constructed according to our invention ma be carried to any height desired, the joints between the vertical columns and the horizontalbeams being disposed at eachiloor level as in the case of buildings as now constructed.

From the foregoing description we believe that the details of construction of our invention will be readily understood and We will therefore now proceed to describe the method employed in constructing such a building. It is preferable in carrying out the invention that the columns and tically disposed plates 39 at their opposite fhorizontalbeams be formed at the factory ends, the p ates 39 carrying vertically' spaced ton e members 40 and 41 of a'coiistruction similar to the tongues 28 and 29 on the cross beam 26. The tongues 40 and 41 are engned within the sockets of the members 36 an 37 respectively when the beams 38 are placed in position in the building. Y

The plates 27 are provided with vertically extending integral sleeve portions 42 and 43 which are formed with the side edges of the plate and which extend from the upper end to a point midway of1the length thereof. The plates 39 are formed with sleeve portions 44. and 45 similar in construction to the sleeves 42 and 43, and extending from a point midway o f the sides of the plate 39 to the lower end thereof. It will be readily seen from an inspection of Figs. 1, 2 and 4 that when the beams 26 and 38 are in place in the building structure, the sleeves 42 will be disposed in aliiiement with the sleeves 44 so that a taperedl locking pin 46 may be driven into the sleeves so as to further lock the parts against relative movement. I

In the case Where the upright columns are disposed inwardly of the building structure sothat horizontal beams are secured to the socket members on four sides thereof, each of the right angularly disposed beams would have the sleeve portion thereof locked to the sleeve of the next adjacent beam as explained above with respect to the beams 26 and 38. However,.when the vertical column is disposed at a corner of the building and the cross beams are attached to only two noise which has commonl with their respective tongue and socket members so that it will be unnecessary to do any welding riveting, or cutting at the scene of the building construction. ricatin the building, the lowermost of the vertica columns are placed in position on the foundation 10 and the next superposed u right member of an adjacent pair are p aced in position as shown in FigL. 5, whereupon one of the cross beams is placed in position with the tongue members thereof In fab- .e

engaging the respective sockets on the ad.

jacent ends of the superposed pair of uprights. After this first cross beam has been placed in position it will be unnecessary to artificially support the .uprights of the second story engaged Aby the ends thereof. This operation is then continued until all of the upright members for the second story of the building are locked in position as above described whereuponthe operation may be repeated for the third story of the building and so on until the steel structure has been carried to the desired height.

It will thus be seen that we have provided a steel building structure which may be quickly and easily aembled at the scene of the building operation without necessitating the emplo ment of any special tools, riveting or wel ing machinery, thereby greatly reducing the cost of lthe building operation and practically eliminating the been associated with the construction o structural steel buildings.

Although a preferred embodiment of the with, the sleeves on the plate of adjacent 1nvent1on has been shown and described, beams being disposed in alinement, and a it will be understood that various changes locking pin di in the details of construction may be made 5 without departing from the spirit of the invention as defined by the appended claims.
